The UFC dramatically announced the matchup Friday to close a news conference promoting the slate of fight cards for the rest of 2018.

McGregor won the featherweight and lightweight championships during his meteoric MMA career, but he hasn’t fought in the UFC since taking the lightweight belt from Eddie Alvarez in November 2016.

McGregor hasn’t competed at all since losing his incredibly lucrative boxing match against Floyd Mayweather in August 2017.

McGregor also has resolved his legal troubles after throwing a hand truck at a bus containing UFC fighters last April. Nurmagomedov was the intended target of his misbehaviour after a previous spat between the fighters’ camps.
